Main Materials of Single-ended Hexagon Studs

Carbon Steel: Such as AISI1045 carbon steel, which is relatively low-cost, has certain strength and hardness, and its performance can be improved through heat treatment. It is widely used in general mechanical connections, construction, and other fields.
Alloy Steel: Such as 35CrMo, 30CrMo, AISI4140, AISI4145, etc. It has high strength, high toughness, and good wear resistance and corrosion – resistance, and is often used in key parts under high-temperature, high-pressure, and high-load conditions.
Stainless Steel: Commonly seen types are 304, 316, AISI410, etc. It has good corrosion resistance, heat-resistance, and oxidation-resistance and is suitable for humid and corrosive environments, as well as industries such as food and medical.
Copper: Including brass, etc. It has good electrical conductivity, thermal conductivity, corrosion resistance, and workability. It is relatively soft and is often used in electronic and electrical equipment, as well as in occasions where anti-magnetic and anti-static properties are required.
Inconel 718: It belongs to nickel-based superalloys. It has good machinability, high tensile strength and creep resistance at high temperatures, and also has good corrosion-resistance. It is often used in aerospace, energy, and other fields.

Electroplating: The stud is immersed in an aqueous solution containing the metal compound to be deposited. An electric current is passed to make the metal precipitate and deposit on the stud, such as nickel plating, zinc-plating, chromium-plating, etc. Nickel – plating can improve wear – resistance, corrosion – resistance, and electrical conductivity. Zinc plating has a low cost and good rus -prevention ability. Electro-galvanized coatings are thin and have a bright appearance, while hot – dip galvanized coatings are thick and have good corrosion-prevention performance.
Electroless Plating: In the absence of an electric current, a metal coating is deposited on the surface of the stud through a chemical reduction reaction. For example, electroless nickel – plating has a uniform coating, low porosity, and good corrosion-resistance and wear-resistance.

Blackening Treatment: A common method for single – ended hexagon studs made of steel. A black oxide film is formed on the surface through chemical or heat treatment, which can improve corrosion resistance and also enhance the appearance. It is used for mechanical parts with general requirements.
Phosphating Treatment: A phosphate chemical conversion film is formed on the surface of the stud, which can improve corrosion resistance, lubricity, and paint adhesion. It is often used in occasions where subsequent painting is required or there are certain corrosion-resistant requirements.

Spraying: It can be sprayed with paint, powder coatings, etc. Paint spraying can provide a variety of colors and decorative effects. Powder coatings have a thick coating, good corrosion resistance, and wear resistance, and are suitable for environments with high requirements for appearance and corrosion resistance.
Dacromet Treatment: A mixed solution of zinc powder, aluminum powder, etc. is coated on the surface of the stud, and after baking, a flaky metal coating is formed. It has excellent corrosion resistance and no hydrogen embrittlement and is often used in the automotive and power industries.

Sand (Shot) Blasting Treatment: Sand grains or steel shots are sprayed onto the surface of the stud at high speed by a sandblaster to remove oxide scale, burrs, etc., roughen the surface, improve the coating adhesion, and also improve the surface stress state.
Polishing Treatment: It includes mechanical polishing, chemical polishing, and electrochemical polishing. Mechanical polishing makes the surface smooth through mechanical means such as polishing wheels. Chemical polishing and electrochemical polishing use chemical reactions or electrolysis to make the surface flat and bright, which can improve the surface finish and aesthetics.

Machinery Manufacturing: Used to connect various mechanical parts, such as engine blocks, transmission casings, etc.
Electronics and Electrical Appliances: Used to fix the motherboard in a computer case, and can also be used to connect the outer shell and internal components of electrical equipment.
Furniture Manufacturing: Used to assemble furniture such as tables, chairs, and cabinets, connecting different boards.
